SIMPLER WORKAROUND: I just discovered that removing the "d::" symlink completely works (or don't create it in the first place), as long as the read-only .iso FS is loop mounted where "d:" indicates. (Contrary to the appdb "Howto" instructions.)
This suggests that there's no bug in Wine and that the Howto should be fixed instead.
